Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting device used for connecting two members, for example, an inner sliding door and an outer sliding door of a cabinet.

[0002]

2. Description of the Related Art There are various types of connecting devices which can connect two members, for example, an inner sliding door and an outer sliding door of a cabinet, or can release the connection. Among these, for example, Japanese Patent Application Laid-Open No. 8-232926 discloses an attachment (connection device) that can easily perform the connection and the release thereof. Such attachment 100
As shown in FIG. 9, is composed of an outer member 101 and an inner member 102.
By being inserted into the slot 104a, it can be connected to the wall surface forming member 103. That is, a C-shaped groove 103a having a cylindrical inner peripheral surface is provided in the wall surface forming member 103 along the longitudinal direction, and the T slot 104a along the axial direction is formed in the groove 103a. The columnar bar member 104 is inserted. On the other hand, the outer member 101 of the attachment 100 has a box shape with an open front surface, and a pair of leg pieces 101b capable of protruding into the T-slot 104a are projectingly provided on the rear wall 101a.
Each free end of 01b is provided with an outward projection 101b ₁ which can be engaged with the inside of the T-slot 104a, and the inner member 102 of the projection 102b can be inserted between the pair of leg pieces 101b. The outer member 101 can be telescopically inserted. In such an attachment 100, the inner member 102 is attached to the outer member 10
1 is pushed to the end, the back piece 102a becomes a pair of leg pieces 1.
Since the leg pieces 101b are prevented from inwardly deforming by intervening between 01b, the attachment 100 cannot be separated from the T slot 104a and is connected to the wall surface forming member 103. When the connection is released, the inner member 102 is pulled out from the outer member 101, and further the outer member 101 is pulled out from the T slot 104a.

[0003]

However, even though the attachment 100 of the above-mentioned example can be easily connected and released, for example, in the case of connection, the T-slot 104a of the wall-constituting member 103 is provided with the outer member 101. It is necessary to insert the leg piece 101b and then push the check piece 102a of the inner member 102 between the leg pieces 101b, and when the outer member 101 and the inner member 102 are pushed together, the connection is completed. Since it is not a thing, there is room for further improvement so that it can be performed quickly with one touch.

An object of the present invention is to provide a connecting device capable of quickly connecting and disconnecting two members with one touch.

[0005]

In order to solve the above-mentioned problems, a connecting device for a member according to claim 1 of the present invention comprises a shaft portion arranged on one of the two members and another member on the other side. And a bearing portion disposed in the member, and the above-mentioned shaft portion composed of a plurality of locking members and a movable member arranged so as to be capable of advancing and retracting between the locking members is The locking member and the movable member are integrally inserted into the opening portion of the bearing portion described above, and from the peripheral edge of the opening portion to the side opposite to the insertion side of the shaft portion in a mode against insertion of the shaft portion. While the locking member of the shaft portion is locked to the elastic piece of the protruding bearing portion, both members are connected, while the movable member of the shaft portion is retracted, and the bearing portion of the locking member of the shaft portion is retracted. By releasing the engagement with the elastic piece, the connection between both members is released. According to the present coupling device, the two members can be coupled because the locking member of the shaft portion is locked to the elastic piece of the bearing portion only by inserting the shaft portion into the bearing portion, while the movable member is movable. Since the connection between the two members can be released only by retracting and releasing the locking, the connection between the two members and the release of the connection can be performed quickly with one touch.

In the member connecting device according to the second aspect of the present invention, the moving means for retracting the movable member when releasing the connection between the two members is a gear mechanism or a cam mechanism for engaging with the movable member. It was designed to enable quick disconnection.

Further, the shaft portion 42 is circumferentially equally divided by the slit 43a from the tip end to the substantially central portion along the longitudinal direction, and in the present embodiment, three small protrusions (locking members) 43b.
And a hollow cylindrical guide member 43 that is divided into two parts, and is movably arranged in the hollow of the guide member 43. When the shaft portion 42 is inserted into the bearing portion 41 and the members 2 and 3 are in a connected state, The small projecting piece 43b is provided with a cylindrical guided member (movable member) 44 that supports the small protruding piece 43b so as not to be bent inward by receiving force from the elastic piece 41b. Incidentally, the small protrusion 4
The tip of 3b is tapered for convenience of insertion into the bearing portion 41.

How to use the connecting device 40 will be described with reference to FIG. In order to bring the two members 2 and 3 that have been disconnected by the device 40 into the connected state, the guided member 4 of the shaft portion 42 is used.
4 by directly grasping with a hand or by using an appropriate moving means, to advance into the hollow of the guide member 43 or in a mode in which it slightly projects from the hollow to cover the small projecting piece 43b of the guide member 43. Shaft 4 supported by guide member 44
2 into the opening 41a of the bearing 41 and its elastic piece 41b.
It can be inserted against. At this time, the elastic piece 41b
The locking force acting on the guide member 43 acts to prevent the shaft portion 42 from coming out of the bearing portion 41, so that the shaft portion 42 is engaged with the bearing portion 41, and both members 2 , 3 will be connected with one touch. However, when the two members 2 and 3 are released from the connection, the guided member 44 may be directly grasped by a hand or retracted by using an appropriate return means such as a spring, and the elastic piece may be moved in accordance with the retreat. Since the locking of 41b with respect to the guide member 43 is released, the shaft portion 42 can be easily pulled out from the bearing portion 41, and the connection of both members 2 and 3 is released.
That is, the connection between the two members 2 and 3 can be released only by retracting the guided member 44 and releasing the locking.

The timing of advancing the guided member 44 into the hollow of the guide member 43 is delayed so that the guide member 43 is first inserted into the opening 41a of the bearing portion 41 and then the guided member 44 is advanced. Alternatively, in this way, the drag force from the elastic piece 41b at the time of insertion is reduced, so that smooth insertion can be performed, as described above.

[0028]

According to the connecting device of the present invention, by simply inserting the shaft portion into the bearing portion, the locking member of the shaft portion is locked to the elastic piece of the bearing portion, so that the two members are connected. On the other hand, since the connection between the two members can be released only by retracting the movable member and releasing the locking, the connection between the two members and the release of the connection can be performed quickly with one touch.
